Upgrading the glibc Version

Purpose

The default glibc version is 2.17, which has poor performance in memory data copy on ARM servers and may cause performance differences in memory performance-sensitive scenarios. You can upgrade the version to 2.31 to improve the performance.

Procedure

1. Download the latest glibc version (glibc 2.28 or later is recommended).

   Go to https://sourceware.org/git/?p=glibc.git, find the required glibc version under tags, and click the corresponding tag.

   

   The download link of the installation package is displayed.

   

2. Perform compilation and installation.

   1 2	./configure -prefix=/opt/glibc-2.31 make && make install

3. When compiling the Nginx and ATS applications, specify the glibc version as 2.31.

   1	CFLAGS="-I/opt/glibc-2.31/include" LDFLAGS="-L/opt/glibc-2.31/lib/ -Wl,-rpath=/opt/glibc-2.31/lib/ -Wl,--dynamic-linker=/opt/glibc-2.31/lib/ld-2.31.so"
